Heshun supplies transparent film which covers the biggest output capacity due to the most widespread industrial applications, the thickness range from 12u to 500u, width in master or slitting rolls, with high tensile strength, dimension stability, optical clarity, and precision properties.
Transparent PET film offers a wide range of applications due to its optical properties, mechanical strength, and chemical resistance. Its versatility makes it a popular choice as a clear polyester film in industries such as packaging, electronics, printing, and graphics.
Transparent PET Film is made by polymerization of Purified Terephthalic Acid (PTA) and Monoethylene Glycol (MEG) under specific temperatures and pressure to form PET pellets.
The PET pellets are then melted down and pushed through a dyeing machine to obtain a flat sheet.
The next step involves stretching the sheet to align the molecules to make it stronger and more stable. Two methods of orientation are Tentering and Bubble blowing.
The oriented PET film is annealed or treated with heat to stabilize the film and acquire its properties. The film is cooled and rolled into large spools to be further processed or cut as per the requirement.
